Yeah, I was wondering how someone would go about that, too. I don't understand why they can have a product like PB2 and not AB2 (almond butter2) or CB2 (cashew butter2). I absolutely adored PB2 for a while, and was sad to let it go when trying to get into a more whole foods approach to my lifestyle. I will be patiently waiting for scientists to create other versions of PB2... until then, I just soak almonds in water to help rid them of some poisons, and just try not to worry about things tooooo much.
If you're really missing peanut butter or a spread of that type, though, I've found that pumpkin puree mixed with some coconut oil, coconut flakes, and a bit of honey is a great spread for apples, bananas, or celery. it's got a creamy texture to it, and the pumpkin flavor is so mild that the coconut comes through really lightly. I'm sure you could try another oil like macadamia nut oil, if you wanted? But maybe that'd defeat the purpose of making the spread in the first place lol.
